CrystaL: Spontaneous Emergence of Visual Latents in MLLMs
Multimodal Large Language Models (MLLMs) have achieved remarkable performance by integrating powerful language backbones with large-scale visual encoders. Among these, latent Chain-of-Thought (CoT) methods enable implicit reasoning in continuous hidden states, facilitating seamless vision-language integration and faster inference. However, existing heuristically predefined supervision signals in latent CoT provide limited guidance for preserving critical visual information in intermediate latent states. To address this limitation, we propose CrystaL (Crystallized Latent Reasoning), a single-stage framework with two paths to process intact and corrupted images, respectively. By aligning the attention patterns and prediction distributions across the two paths, CrystaL crystallizes latent representations into task-relevant visual semantics, without relying on auxiliary annotations or external modules. Extensive experiments on perception-intensive benchmarks demonstrate that CrystaL consistently outperforms state-of-the-art baselines, achieving gains in fine-grained visual understanding while maintaining robust reasoning capabilities.

Addressing Latent CoT Limitations
Multimodal Large Language Models (MLLMs) leverage latent Chain-of-Thought (CoT) for seamless vision-language integration. However, existing latent CoT methods struggle with predefined supervision signals that poorly guide the preservation of critical visual information in intermediate states. Previous approaches often resort to external models or human annotations (CoVT, Monet), leading to heuristic and task-dependent solutions, or require complex multi-stage training (LIVR). CrystaL addresses this by ensuring latent tokens are functionally aligned with the final generation objective in a single, self-supervised stage, preventing semantic information loss and hallucination.
CrystaL's Dual-Path Latent Crystallization
CrystaL introduces a novel single-stage dual-path framework for robust latent reasoning. It comprises an intact path for high-fidelity images and a corrupted path for visually degraded inputs. Key to CrystaL is the Stochastic Image Corruption (SIC) module, which applies diverse corruption primitives (Gaussian blur, random mask, color distortion, noise) to create degraded observations. Latent representations from the intact path are copied to the corrupted path. Two primary objectives enforce consistency: Predictive Distribution Consistency (Lkl) minimizes KL divergence between output distributions of both paths, ensuring robust decision-making despite degradation. Mechanistic Consistency (Lattn) aligns cross-path attention patterns over visual latent tokens, grounding reasoning in visual content.
State-of-the-Art Performance & Data Efficiency
CrystaL consistently achieves state-of-the-art results across perception-intensive benchmarks, demonstrating superior fine-grained visual understanding and robust reasoning. It attains an average score of 75.4%, outperforming strong baselines like CoVT and LIVR. Notably, CrystaL shows significant gains in high-resolution perception, with +4.8% on 4K HRBench and +6.2% on 8K HRBench compared to Qwen2.5-VL-7B. Furthermore, CrystaL exhibits exceptional data efficiency, achieving state-of-the-art accuracy with only 16k training samples, a 6x reduction compared to methods like SKILA (100k samples). This highlights CrystaL's ability to achieve superior multimodal understanding with significantly less data.
Optimizing Latent Token & Corruption Strategies
Ablation studies reveal critical insights into CrystaL's design. Regarding latent token configurations, using diverse token types consistently outperforms identical ones, emphasizing the importance of semantic variety. An optimal balance is achieved with 8 tokens. The alignment strategy analysis highlights the necessity of both Predictive Distribution Consistency (Lkl) and Mechanistic Consistency (Lattn) for peak performance, as combining them yields the best results. For image corruption strategies, Gaussian blur consistently leads to the best performance across benchmarks, striking the ideal balance between information suppression and semantic preservation, unlike spatial perturbations that can introduce artificial edge artifacts.

Enhanced Spatial Reasoning: CrystaL vs. CoVT
In a challenging CVBench-2D scenario, a user asks: 'Considering the relative positions of the cutlery and the range in the image provided, where is the cutlery located with respect to the range?'
CoVT's Approach: Utilizes external modules like segmentation, depth maps, and DINO features. It incorrectly answers 'It is to the left of the range.'
CrystaL's Approach: Leverages its internal '<visual latent tokens>' for reasoning. It correctly identifies the cutlery's position, answering 'It is to the right of the range.' This demonstrates CrystaL's ability to achieve more accurate spatial-relational understanding without relying on external, predefined features.
